timer

I'm using ATMEGA8 for my project. I want to make a LCD display a clock. The below code works fine and displays a code in proper format on the LCD. But the problem is the timer/counter is not getting synced with real clock, it is having 2-3 second difference with the real time on my watch. I've...

Hello Guyz, I've found below code that belongs to the timer declaration function but the definition is hidden by the author. Can anyone help me to provide a definition for the same? I want this to be utilized in a project related to ATMEGA8 using Atmel studio. #ifndef TIMERS_H_ #define...

this doesn't work: TIM1_CCMR2 = 0b01; //its default input channel TIM1_IER = 0b100; //channel 2 capture interrupt TIM1_CCER2 = 0b1; //channel 2 capture TIM1_CR1 = 0b1; //start counter and yet this works with no problem (on channel 1) TIM1_CCMR1 = 0b10; //remap channel 1 on input 2 where ch2...

I am trying to get an external timer (TIM5) to toggle an LED at a certain time period. I am designing it to interrupt every 2 micro seconds. I use an oscilloscope to check whether it works as intended, but unfortunately it does not. The clock speed is 45Mhz And I calculate the period APBtimer...

Hi Experts, Like to know, I'm preparing a Peltier Cooler with TEC1 12706, & in same I found Cooling side started getting Hot after sometime, So is there any formula/Calculation or Circuit suggestion, which provide Constant cooling by turning ON & OFF Peltier at specific time. E.g. when I...

As the title describe. What do you think is the simplest way to generate 2ch clock 180 degree phase shift with 40% duty cycle and 500kHz frequency without any mcu/serial config input? Using two 555 cmos timers seems not like to optimal solution.

There is a peculiar issue noticed, I need help understanding the reason and may be troubleshooting. There is a microcontroller(87S52) based board with ADC and IO lines. The unit is programmed to operate for a time lets say T secs. When the board is used in the system in stand alone mode, I tend...

Having repaired an old Kambrook KD36 timer gifted to me by a friend, I'm sharing my circuit schematic and notes for anyone who might find them useful. The timer had been rendered unserviceable due to acid leakage from the two back-up batteries. The leaking acid had damaged some areas of the PCB...

Hello, what i have in my circuit is 2 push buttons, the first for starting a timer of 3 seconds which then when the timer is done it sends a 1 to the NRF24L01 which turn a relay on for a specific time which is 3 seconds then turn it off by sending 0 to NRF24L01. The second button is reset button...

i want to use pwm in my project. I am using pic16f18875 controller and xc8 compiler. i have configured the pwm and i was configuring timer 2 for that. But i am not getting the pwm output. I am trying to understand the use of register TxRST in timer.I want to understand the use of TxRST...

Using PIC16F18446 TMR0 module to create a 1 second delay WITHOUT the use of the interrupts. Here is the program so far: void main(void) { // Oscillator Settings: // HFINTOSC 8 MHz OSCCON1 = 0b01110100; OSCFRQ = 0b00000011; // Data Direction Settings TRISA =...

Hi I need help building the electronics for a home project. Essentially I am trying to: 1. Charge a battery with a solar panel 2. Activate a 12solenoid valve controlling pressurized water with a push button 3. Have the solenoid close after an adjustable time delay I was able to find solar...

I am looking to install a delay timer in a simple 12v circuit that supplies a well pump (6A) in a garden powered from a solar charged battery. I want the pump to run for 10mins when a circuit is closed on a toggle switch. If the pump is to restart after it has stopped, the toggle will need to...

Hi, I know this is a simple one for most of you but I’m quite new to this so please be gentle. I have an old pallet wrapper that I would like to automate. I still want to be able to use it in it’s current form so was going to start with a “manual/ auto” selector switch after the turntable has...

I need to make a digital counter circuit which it counts to 15 minutes for my big project in my campus . When the circuit counts to 10 minutes, it will rings a buzzer. Same when it continues to 15 minutes, it will ring a buzzer again. (the circuit is for public speaking, so the speaker knows...
